GENERAL DESCRIPTION
The AD8353 is a broadband, fixed-gain, linear amplifier that
operates at frequencies from 1 MHz up to 2.7 GHz. It is
intended for use in a wide variety of wireless devices, including
cellular, broadband, CATV, and LMDS/MMDS applications.
By taking advantage of ADI’s high performance, complementary Si
bipolar process, these gain blocks provide excellent stability
over process, temperature, and power supply. This amplifier is
single-ended and internally matched to 50 Ω with a return loss
of greater than 10 dB over the full operating frequency range.
The AD8353 provides linear output power of 9 dBm with 20 dB
of gain at 900 MHz when biased at 3 V and an external RF
choke is connected between the power supply and the output
pin. The dc supply current is 42 mA. At 900 MHz, the output
third-order intercept (OIP3) is greater than 23 dBm and is
19 dBm at 2.7 GHz.

The AD8353 can also operate with a 5 V power supply; in
which case, no external inductor is required. Under these
conditions, the AD8353 delivers 8 dBm with 20 dB of gain at
900 MHz. The dc supply current is 42 mA. At 900 MHz, the
OIP3 is greater than 22 dBm and is 19 dBm at 2.7 GHz. The noise
figure is 5.6 dB at 900 MHz. The reverse isolation (S
The AD8353 is fabricated on ADI’s proprietary, high performance,
25 GHz, Si complementary, bipolar IC process. The AD8353 is
available in a chip scale package that uses an exposed paddle for
excellent thermal impedance and low impedance electrical
connection to ground. It operates over a −40°C to +85°C
temperature range, and an evaluation board is also available.
